Accounting Policies [Abstract]
Basis of Presentation	NOTE 1 – BASIS OF PRESENTATION:
	Graham Corporation’s (the “Company’s”) Condensed Consolidated Financial Statements include: (i) its wholly-owned foreign subsidiary located in China; and (ii) its wholly-owned domestic subsidiary located in Lapeer, Michigan. The Condensed Consolidated Financial Statements have been prepared in accordance with accounting principles generally accepted in the U.S. (“GAAP”) for interim financial information and the instructions to Form 10-Q and Rule 10-01 of Regulation S-X, each as promulgated by the Securities and Exchange Commission. The Company’s Condensed Consolidated Financial Statements do not include all information and notes required by GAAP for complete financial statements. The unaudited Condensed Consolidated Balance Sheet as of March 31, 2014 presented herein was derived from the Company’s audited Consolidated Balance Sheet as of March 31, 2014. For additional information, please refer to the consolidated financial statements and notes included in the Company’s Annual Report on Form 10-K for the fiscal year ended March 31, 2014 (“fiscal 2014”). In the opinion of management, all adjustments, including normal recurring accruals considered necessary for a fair presentation, have been included in the Company’s Condensed Consolidated Financial Statements.
	The Company’s results of operations and cash flows for the three and nine months ended December 31, 2014 are not necessarily indicative of the results that may be expected for the fiscal year ending March 31, 2015 (“fiscal 2015”).

Revenue_Recognition

Revenue Recognition	9 Months Ended
	Dec. 31, 2014
Text Block [Abstract]
Revenue Recognition	NOTE 2 – REVENUE RECOGNITION:
	The Company recognizes revenue on all contracts with a planned manufacturing process in excess of four weeks (which approximates 575 direct labor hours) using the percentage-of-completion method. The majority of the Company’s revenue is recognized under this methodology. The percentage-of-completion method is determined by comparing actual labor incurred to a specific date to management’s estimate of the total labor to be incurred on each contract. Contracts in progress are reviewed monthly, and sales and earnings are adjusted in current accounting periods based on revisions in the contract value and estimated costs at completion. Losses on contracts are recognized immediately when evident to management. There is no reserve for credit losses related to unbilled revenue recorded for contracts accounted for on the percentage-of-completion method. Any reserve for credit losses related to unbilled revenue is recorded as a reduction to revenue.
	Revenue on contracts not accounted for using the percentage-of-completion method is recognized utilizing the completed contract method. The majority of the Company’s contracts (as opposed to revenue) have a planned manufacturing process of less than four weeks and the results reported under this method do not vary materially from the percentage-of-completion method. The Company recognizes revenue and all related costs on these contracts upon substantial completion or shipment to the customer. Substantial completion is consistently defined as at least 95% complete with regard to direct labor hours. Customer acceptance is generally required throughout the construction process and the Company has no further material obligations under its contracts after the revenue is recognized.
	Receivables billed but not paid under retainage provisions in its customer contracts were $1,401 and $901 at December 31, 2014 and March 31, 2014, respectively.

	Investments consist solely of certificates of deposit with financial institutions and fixed income debt securities issued by the U.S. Treasury. All investments have original maturities of greater than three months and less than one year and are classified as held-to-maturity, as the Company has the intent and ability to hold the securities to maturity. The investments are stated at amortized cost which approximates fair value. All investments held by the Company at December 31, 2014 are scheduled to mature on or before November 17, 2015.

Inventory Disclosure [Abstract]
Inventories	NOTE 4 – INVENTORIES:
	Inventories are stated at the lower of cost or market, using the average cost method. For contracts accounted for on the completed contract method, progress payments received are netted against inventory to the extent the payment is less than the inventory balance relating to the applicable contract. Progress payments that are in excess of the corresponding inventory balance are presented as customer deposits in the Condensed Consolidated Balance Sheets. Unbilled revenue in the Condensed Consolidated Balance Sheets represents revenue recognized that has not been billed to customers on contracts accounted for using the percentage-of-completion method. For contracts accounted for using the percentage–of–completion method, progress payments are netted against unbilled revenue to the extent the payment is less than the unbilled revenue for the applicable contract. Progress payments exceeding unbilled revenue are netted against inventory to the extent the payment is less than or equal to the inventory balance relating to the applicable contract, and the excess is presented as customer deposits in the Condensed Consolidated Balance Sheets.
	Major classifications of inventories are as follows:
		December 31,		March 31,
		2014		2014

Common shares outstanding include share equivalent units, which are contingently issuable shares. Diluted income per share is calculated by dividing net income by the weighted average number of common shares outstanding and, when applicable, potential common shares outstanding during the period. A reconciliation of the numerators and denominators of basic and diluted income per share is presented below:

Commitments and Contingencies	NOTE 11 – COMMITMENTS AND CONTINGENCIES:
	The Company has been named as a defendant in lawsuits alleging personal injury from exposure to asbestos allegedly contained in products made by the Company. The Company is a co-defendant with numerous other defendants in these lawsuits and intends to vigorously defend itself against these claims. The claims are similar to previous asbestos suits that named the Company as defendant, which either were dismissed when it was shown that the Company had not supplied products to the plaintiffs’ places of work or were settled for immaterial amounts.
	As of December 31, 2014, the Company was subject to the claims noted above, as well as other legal proceedings and potential claims that have arisen in the ordinary course of business.
	Although the outcome of the lawsuits to which the Company is a party cannot be determined and an estimate of the reasonably possible loss or range of loss cannot be made, management does not believe that the outcomes, either individually or in the aggregate, will have a material effect on the Company’s results of operations, financial position or cash flows.

Accounting Changes and Error Corrections [Abstract]
Accounting and Reporting Changes	NOTE 14 – ACCOUNTING AND REPORTING CHANGES:
	In the normal course of business, management evaluates all new accounting pronouncements issued by the Financial Accounting Standards Board (“FASB”), the Securities and Exchange Commission, the Emerging Issues Task Force, the American Institute of Certified Public Accountants or any other authoritative accounting body to determine their potential impact on the Company’s consolidated financial statements.
	In May 2014, the FASB issued guidance related to the accounting for revenue from contracts with customers. This guidance establishes principles for reporting information about the nature, amount, timing and uncertainty of revenue and cash flows arising from a company’s contracts with customers. The guidance requires companies to apply a five-step model when recognizing revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods and services. The guidance also includes a comprehensive set of disclosure requirements regarding revenue recognition. The provisions of the guidance are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2016. The Company is currently evaluating the impact this guidance will have on its financial position, results of operations and cash flows. See Note 2 for a description of the Company’s current revenue recognition policy.
	Management does not expect any other recently issued accounting pronouncements, which have not already been adopted, to have a material impact on the Company’s consolidated financial statements.
